Django DRF REST Put 方法不更新任何内容

Question

在 Django PUT 请求中，当我每周更新位置和小时数的值时，PUT 请求 returns 完全相同的值并且没有更新任何内容。

下面是我的代码，

url

url(
r'^api/availability', views.AvailabilityAPIView.as_view(),name='api_availability'
)

型号

class Availability(models.Model):
    # Skill model which contains trainer's skill details
    user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True)
    locations = models.CharField(max_length=2000)
    hours_per_week = models.IntegerField(default=0)

    def __str__(self):
        return self.locations + "|" + str(self.hours_per_week)

序列化器

class AvailabilitySerializer(serializers.ModelSerializer):
    class Meta:
        model = Availability
        fields = ['user', 'locations', 'hours_per_week']

观看次数

class AvailabilityAPIView(APIView):
    authentication_classes = (CsrfExemptSessionAuthentication, BasicAuthentication)

    def get(self, request):
        availability = Availability.objects.all()
        serializer = AvailabilitySerializer(availability, many=True)
        return Response(serializer.data)

    def put(self, request):
        serializer = AvailabilitySerializer(request.user, data=request.data, partial=True)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data)
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

请帮助理解我做错了什么。我需要从url传递PK并更新具体的吗？

Answer 1

您需要传递 Availability 模型的实例。

def put(self, request):
        instance = Availability.objects.get(user=request.user)
        serializer = AvailabilitySerializer(instance, data=request.data, partial=True)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data)
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
